Abstract
Description
ソース信号と同位相(およそ0°の位相ずれ)を有する位相であり;
低い周波数においてはわずかな振幅しかなく;
オフェンディングクロストーク信号に両方の補償信号の振幅が付加された際に、特定の有利な周波数にて零(又は最低限数)が生成される、高い周波数の振幅を有し;及び
第1補償信号よりも高い率で周波数に応じて増加する振幅(例えば、40dB/ディケード)を有する。
|H(jω)|=ωMZL/√[(ZLZo−ω2(L−M)2−2(L−M)Mω2+L/C)2+(ωL(ZL+Zo)−Zo/(ωC))2]、及び
位相は[H(jω)]=90°−tan−1([Zo/(ωC)−ωL(ZL+Zo)]/[ZLZo−ω2(L−M)2−2(L−M)Mω2+L/C])。
|H(jω)|=ωMZL/√[(ZLZo+L/C)2+(Zo/(ωC))2]=ω2MCZL/Zo、そして位相は
位相[H(jω)]=90°−tan−1(Zo/(ω(CZLZo+L))に減少する。
